Our house (built 1913, but my guess is rewired in 1950s) has the usual 110-220 service. Seemingly randomly, the even-numbered 110V circuits go dark (i.e,, those connected to one or the two hot bus bars in the panel). Neither main breaker flips.
However, turning on the (electric) oven, or turning one of the two larger burners on the stove to high appears to reset the breaker and the circuits go back on. Sometimes they stay on for seconds, sometimes for minutes, sometimes for hours.
I presume I'll have to replace the main breaker. But is there more going on? And why does turning on a 230V circuit reset circuits?
